| This directory contains code for AMD bulldozer including its piledriver update. | |
| We currently make limited use of SIMD instructions, both via the MPN_PATH and | |
| via inclusion of x86_64/fastsse files. | |
| The bd1 cores share one SIMD/FPU pipeline for two integer units. This probably | |
| means that an all-core GMP load (such as a HPC load) might run slower if there | |
| is significant SIMD dependency. | |
| We should perhaps allow a special 'bd1nosimd' pseudo cpu-name excluding any | |
| SIMD code. |
